How to choose a mortgage broker in Sydney

A mortgage broker can compare loans across many lenders and manage the paperwork for you. The catch is that brokers vary a lot, and the one you pick shapes the loan you end up with. This guide gives you a repeatable way to judge any broker, without needing to be a finance expert.

What a broker actually does

A mortgage broker is an intermediary between you and lenders. Instead of applying to one bank, you give your details once and the broker compares options across the lenders on their panel, recommends a loan, and helps you through the application to settlement. In Australia, most borrowers now use this route: brokers arranged around 70 percent of all new residential home loans through 2024, according to the Mortgage and Finance Association of Australia (MFAA).

A good broker saves you time, translates lender jargon, and can match your situation to a lender likely to say yes. A weak broker simply pushes whatever is easy for them. The rest of this guide is about telling the two apart.

1. Check the licence first

In Australia, arranging credit is regulated. A broker must either hold an Australian Credit Licence (ACL) or operate as a credit representative of an ACL holder. This is not optional and it is easy to verify.

  • Ask for their ACL number or the name and number of the licensee they represent.
  • Check it on the ASIC Connect professional registers, which are free to search.
  • Ask which industry body they belong to, such as the MFAA or the FBAA, since membership adds a code of conduct and a complaints path.
  • Confirm they are a member of the Australian Financial Complaints Authority (AFCA), which handles disputes at no cost to you.

If a broker is vague about licensing or cannot point you to a register entry, treat that as a stop sign. Verifiable licensing is the floor, not a bonus.

2. Ask about the lender panel

A broker can only offer loans from lenders they are accredited with, known as their panel. Panel size and makeup matter because they define your real choice.

  • How many lenders are on the panel? Many brokers work with 20 to 40 or more.
  • Which lenders? A healthy panel mixes major banks, second tier banks and non bank lenders, so unusual situations still have options.
  • How often do they use the full panel, versus sending most loans to one or two lenders? Concentration can be a sign of convenience rather than fit.

Most brokers are paid by the lender, not by you, through an upfront commission when the loan settles and a smaller trail commission over the life of the loan. That is normal and legal, but it creates a possible conflict, so transparency is what counts.

PaymentWho paysWhat to ask
Upfront commissionThe lenderDoes it vary by lender, and could that sway the recommendation?
Trail commissionThe lenderIs there any ongoing service in return over the years?
Broker feeYou, sometimesIs a fee charged, and if so, how much and when?

Australian brokers are held to a best interests duty, which legally requires them to act in your best interests. Ask them to explain, in writing, why the recommended loan suits you better than the alternatives they considered.

4. Ten questions to ask before you commit

  • What is your credit licence or credit representative number?
  • How many lenders are on your panel, and which did you compare for me?
  • How are you paid, and will you disclose commissions in writing?
  • Why is this loan in my best interests over the runners up?
  • What are the comparison rate, fees and any break costs?
  • What is your approval and settlement timeframe?
  • Will you handle the lender back and forth, or will I?
  • What happens if my situation changes before settlement?
  • Can you share references or verifiable reviews from clients like me?
  • Who do I contact after settlement if something goes wrong?

5. Red flags to walk away from

  • Pressure to decide today, or to sign before you understand the loan.
  • Only ever recommends one lender, regardless of your situation.
  • Will not put commissions or the comparison in writing.
  • Cannot produce a licence number or register entry.
  • Encourages you to overstate income or understate expenses on the application.
  • Reviews are generic, anonymous or impossible to verify.
One rule above all

Never let anyone talk you into misrepresenting your finances on an application. It is fraud, it puts you in a loan you cannot afford, and it is a clear sign to end the conversation.

Frequently asked questions

Does using a broker cost me more?

Usually the lender pays the broker, so there is often no direct cost to you. Some brokers charge a fee in complex cases. Always ask upfront and get it in writing.

Will a broker always find a better rate than a bank?

Not always. A broker widens your choice and does the legwork, but you should still compare the recommended loan against going direct. The value is in fit and effort saved, not a guaranteed lowest rate.

Can I change brokers if it is not working?

Yes, until you have signed a loan application you are free to walk away. It is your decision and a good broker will respect that.

Next steps

Run your numbers through the budget planner first, then read the guide that matches your situation: first home buyers, refinancing, or self employed and low doc loans. New terms are defined in the glossary.
